Vitamin D refers to a group of fat-soluble secosteroids that play a role in increasing intestinal absorption of calcium, iron, and other essential minerals and nutrients.* For humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol). Vitamin D is sometimes fortified in certain foods, such as milk and cheese, but does not often naturally occur in food sources. Synthesis of vitamin D3 in the skin through sunlight and supplementation with vitamins is the most common source of vitamin D3 for most individuals.
Unlike most other vitamins, the body can make its own vitamin D when skin is exposed to sunlight. This is why vitamin D3 is often referred to as “the sunshine vitamin.” There are two types of vitamin D important for humans: vitamin D2, which is made by plants, and vitamin D3, which is made by human skin when exposed to sunlight.* Vitamin D3 is the most active form of vitamin D found in humans.* Once created from sunlight, the body sends vitamin D3 to the liver to convert it to a substance called 25(OH)D so that it can be sent to the rest of the body as activated vitamin D3.
Activated vitamin D3 may help support healthy calcium levels in the blood and bones as well as support immune health.* However, most people do not get enough vitamin D3 from sunlight, and vitamin D is hard to find in plentiful amounts from food sources. That is why supplementing with Nature’s Lab Vitamin D3 is important to maintaining healthy levels of vitamin D3.*
Vitamin D3 helps the body absorb the minerals calcium and phosphorus from foods, both of which may be important for developing the structure and strength of bones and teeth.* That means that even diets with large amounts of calcium and phosphorus still need sufficient amounts of vitamin D3 so that they can be absorbed by the body. Additionally, vitamin D3 may help regulate neuromuscular function and protein synthesis, both of which may support healthy muscle function.*
In addition to supporting healthy bones and muscles, vitamin D3 may also promote a healthy immune system.* The immune system defends the body from foreign organisms that may lead to various harmful health conditions. Vitamin D plays a role in activating the immune system’s T-cells, which are responsible for identifying and defending the body against harmful organisms.*
